Poll: Should Xorg change from using Ctrl+Alt+Backspace to something harder for users to press by accident?

My vote is a "No" (actually a Yo)

After having read this bug, I understand that ctrl+alt+backspace might
be a problem for emacs users. 

however, I'm using vim, and there is no such problem. And I don't want
to learn another combination just due to the emacs users. And then there
might be another application that uses the x-y-z-foo-bar key combo now
used to zap the x server.

I think the way to go is to have an optional config option "ZAP-combo"
that can overwrite the default ctrl+alt+backspace sequence. Then, any
emacs user can change it to what (s)he does like.

I did actually ZAP the X server "accidentally", but that in that case,
"accidentally" means I wanted to zap it, and after wards, figured out it
actually was a bad idea ... changing the key-combo won't help there.

just my € 0.02
